btreetransplant

Instructions

In order to move subtrees around within the binary search tree, write a function, BTreeTransplant, which replaces the subtree started by node with the node rplc in the tree given by root.

Expected function

func BTreeTransplant(root, node, rplc *TreeNode) *TreeNode {

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
	"piscine"
)

func main() {
	root := &piscine.TreeNode{Data: "4"}
	piscine.BTreeInsertData(root, "1")
	piscine.BTreeInsertData(root, "7")
	piscine.BTreeInsertData(root, "5")
	node := piscine.BTreeSearchItem(root, "1")
	rplc := &piscine.TreeNode{Data: "3"}
	root = piscine.BTreeTransplant(root, node, rplc)
	piscine.BTreeApplyInorder(root, fmt.Println)
}

And its output :

$ go run .
3
4
5
7
$
